A sensor stores each value recorded as a double in a line of a file named doubleLog.txt. Every now and again a reading may be invalid, in which case the value "invalid entry" is recorded in the line. As a result, an example of the contents of the file doubleLog.txt could be
20.0
30.0
invalid entry
invalid entry
40.0
Write java code that will process the data from each line in the file doubleLog.txt. The code should print two lines as output. On the first line, it should print the maximum reading recorded. On the second line, it should print the number of invalid entries. As an example, the result of processing the data presented in the example is
Maximum value entered = 40.0.
Number of invalid entries = 2
Note the contents shown in doubleLog.txt represent an example. The program should be able to handle files with many more entries, one entry, or zero entries.
Answers
The provided Java code processes the data from each line in the file doubleLog.txt and prints the maximum reading recorded and the number of invalid entries.
Here's the Java code that processes the data from each line in the file doubleLog.txt and prints the maximum reading recorded and the number of invalid entries:
```java
import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
public class SensorDataProcessor {
public static void main(String[] args) {
String filePath = "doubleLog.txt";
double maxReading = Double.MIN_VALUE;
int invalidCount = 0;
try (BufferedReader reader = new BufferedReader(new FileReader(filePath))) {
String line;
while ((line = reader.readLine()) != null) {
try {
double value = Double.parseDouble(line);
maxReading = Math.max(maxReading, value);
} catch (NumberFormatException e) {
if (line.equals("invalid entry")) {
invalidCount++;
}
}
}
System.out.println("Maximum value entered = " + maxReading);
System.out.println("Number of invalid entries = " + invalidCount);
} catch (IOException e) {
System.out.println("An error occurred while processing the file: " + e.getMessage());
}
}
}
```
In the code, the `filePath` variable specifies the path to the doubleLog.txt file. The `maxReading` variable is initialized with the minimum possible value of a double. The `invalidCount` variable is initialized to 0.
The code utilizes a `BufferedReader` to read the file line by line. Inside the `while` loop, each line is checked. If the line can be parsed as a double value, it is compared with the current maximum reading using the `Math.max()` method to update the `maxReading` if necessary. If the line is equal to "invalid entry," the `invalidCount` is incremented.
Finally, outside the loop, the maximum reading and the number of invalid entries are printed as output using `System.out.println()`.
This code is designed to handle files with varying numbers of entries, including zero entries. It will correctly process the data and provide the desired output based on the contents of the doubleLog.txt file.

People who use a/an contextual design logic believe that the given context determines what type of communication is appropriate.
Contextual design logic emphasizes the importance of considering the specific situation, environment, and audience when determining the most effective and appropriate means of communication. It recognizes that different contexts require different communication strategies and channels to convey information effectively.
By adopting a contextual design logic, individuals or organizations take into account factors such as cultural norms, social dynamics, communication goals, and the characteristics of the intended recipients. This approach helps ensure that the communication is tailored to the specific context, taking into consideration factors such as language, tone, medium, and level of formality.
Contextual design logic encourages a more nuanced and adaptable approach to communication, recognizing that what may be suitable in one context may not be effective or appropriate in another. It promotes sensitivity and responsiveness to the context in order to achieve clear, meaningful, and impactful communication.

Developers in your company need to interact with AWS from the Command Line Interface. Which security item will you need to provide to the developers
Answers
Developers in your company will need to provide an access key ID and a secret access key to interact with AWS from the Command Line Interface. These keys are used to authenticate the user and authorize access to the necessary AWS resources.
The access key ID is a unique identifier that is used to identify the user or application making the request, while the secret access key is a secret code used to sign requests and verify the authenticity of the user or application.
It is important to keep the access key ID and secret access key secure, as they provide access to your AWS resources. Best practices include restricting access to the keys to only those who need them, rotating the keys periodically, and revoking access to the keys when they are no longer needed.

Authentication is concerned with determining _______.
Answers
Authentication can be described as the process of determining whether someone or something is, in fact, who or what it says it is. Authentication technology serves us to access control for systems by checking to see if a user's credentials match the credentials in a database of authorized users or in a data authentication server.
There are three basic kind of authentication. The first is knowledge-based — something like a password or PIN code that only the identified user would know. The second is property-based, meaning the user possesses an access card, key, key fob or authorized device unique to them. The third is biologically based.

Which network protocol allows administrators to access a remote computer in a secure way?
Answers
SSH, also known as Secure Shell or Secure Socket Shell, is a network protocol that gives users, particularly system administrators, a secure way to access a computer over an unsecured network.
What is Secure Shell ?The Secure Shell Protocol (SSH) is a cryptographic network protocol that allows network services to be operated securely over an unsecured network. Remote login and command-line execution are two of its most notable applications. SSH applications use a client-server architecture to connect an SSH client to an SSH server.
SSH is a layered protocol suite that consists of three major hierarchical components: the transport layer provides server authentication, confidentiality, and integrity; the user authentication protocol validates the user to the server; and the connection protocol multiplexes the encrypted tunnel into multiple logical communication channels.
SSH was created on Unix-like operating systems to replace Telnet and unsecured remote Unix shell protocols like the Berkeley Remote Shell and the related rlogin and rexec protocols, which all use insecure, plaintext authentication token transmission.

Explanation:
On-premise solutions typically require a dedicated server room or data center to house the necessary equipment, which can be costly to set up and maintain. In addition, organizations must ensure that their IT staff have the necessary expertise to manage and maintain the on-premise infrastructure. Compared to cloud computing, on-premise solutions also generally have less flexibility and agility. Cloud computing allows for easy scalability, rapid deployment of new services, and the ability to pay for only what you use. On-premise solutions may not be able to match this level of flexibility, particularly for smaller businesses or organizations with limited IT resources.
